Application Method
Apply residual insecticide to areas where wasps typically build nests as preventative measure before nesting season begins. Treat eaves, soffits, porch ceilings, deck undersides, shed interiors, attic spaces, and other protected areas where wasps built nests in previous years. Use pyrethroid spray or microencapsulated formulation with extended residual. Apply as crack and crevice or surface spray to areas where queens search for nest sites in spring. Prevents nest establishment by killing queens as they explore potential nesting locations. Much easier and safer than treating established nests with thousands of wasps.
Timing
Apply in early spring (March-April) before wasp queens emerge from overwintering and begin nest construction. Reapply in early summer if needed.
Frequency
Annual application in early spring. May need mid-season reapplication (June-July) if new nests observed or product residual degraded.
Preparation Required
Identify all previous nest locations and likely nesting sites. Note all eaves, overhangs, and protected areas. Have ladder and safety equipment ready. Select appropriate product with good residual.
Follow-up Required
Monitor treated areas for wasp activity and new nest construction. Retreat if nests appear. Document nest locations for next season preventative treatment. Consider exclusion work to seal entry points to attics and wall voids.
Safety Precautions
- Requires licensed pest management professional for exterior treatments
- Use ladder safely when accessing high areas
- Avoid over-application in enclosed spaces
- Do not apply to food contact surfaces
- Ensure adequate ventilation in enclosed areas
